It was 2 a.m. when the cursor blinked and I realized a single click had just decided an ending. My hands hovered; the room felt smaller. The screen kept its silence while the game did something I couldn’t take back.
I’m speaking from runs, replays, and enough forum posts to know the cheap thrills and the traps. You and I will move through every achievement, ending, and oddball requirement — the ones Steam threads mention and the ones only whispered in Discord channels. I’ll point out exact steps, the little inputs that change endings, and where community tools like Steam’s screenshot/export and Moyens I/O guides can save you hours.
How to complete every achievement in Yunyun Syndrome Rhythm Psychosis
I once failed the prologue because I didn’t read the desktop items. The prologue holds a surprising number of early achievements and it’s where momentum forms.
Start here: treat the prologue as a checklist. Inspect Qtie’s room, unzip files when prompted, and don’t underestimate the value of the energy drink. If you want a clean path through the game’s branching systems, the prologue achievements will give you both toys and traps to manipulate.
| Achievement | How to Complete |
|---|---|
| YUNYUN DENPA OTW! | Finish a rhythm game for the first time |
| Time to explore! | Inspect anywhere in Qties room |
| POWAAHH! MWAH <3 ! | Drink an energy drink |
| Full Combo! YUN ROCK! | Achieve a full combo at least once |
| Yunyun denpa signal SEND! | You need to max out the “#Qtie’s sh^tposts are special codes that predict earthquakes with yun frequencies” trend |
| Y-unzip! | Unzip the folder located at the top right side of the desktop. Password is “rim de lacent” |
| YUN DIE | Drag yunyun into the trash 4 times in a row |
| There is no next time. | You have to get the YUN DIE ending 3 times in a row |
| Don’t leave me all alone…yu.un | Go into room search and wait for 30 seconds. Once you get the text prompt, just play a song |
| Yun are an idiot. | Keep opening and closing the HEEERE’s MOMMY MODE by using the TAB key until you get a rare screen |
| Q † CHANNEL | Complete the prologue |
How do I get all endings in Yunyun Syndrome Rhythm Psychosis?
Every major ending ties back to social-trend meters and precise desktop actions. You’ll be toggling trends, throwing Yunyun around, and sometimes filling save slots to trigger meta endings.
IF? Endings
I watched the trend meter flip while a single song finished; suddenly the whole branch opened. The IF? endings are driven by 5* trend max-outs and small gestures that act like forensic keys.
Each IF? ending corresponds to a specific 5-star trend. Max the listed trend, then complete the final trigger action when required—press ctrl+enter for debug features, export images for some endings, or move Yunyun to specific screen positions. Community resources on Steam and X (Twitter) will help you track which trends are easiest to push on a given run.
How do I trigger the debug menu?
Max the “#Tinfoil hats…” trend, then press ctrl+enter and use the tinfoil-hat keyboard. That’s the specific combination the community confirms on Discord and Steam guides.
True Endings
I’ve seen players hold the controller and refuse offers on-screen; that single refusal swung a true ending. True endings need sustained conspiracy influence and a few intentional misses or rejections.
To reach the true ending you’ll need at least 70% conspiracy influence and to manipulate misses and choices in the exact order the game expects. Read the diaries, export content, and complete follow-up conspiracy trends after the initial true ending to wrap up related achievements.
| Achievement | How to Complete |
|---|---|
| Yunyun Syndrome | Have at least 70% conspiracy influence |
| Clearly Paranoid Qtie | Miss every note in two charts. This will allow patootie to get more conspiracy influence. |
| DONIDEMONARE | Reject yunyun’s offer to delete herself after patootie is defeated. |
| Engage Link | Complete all conspiracy trends after getting the true ending. |
What are the requirements for the true ending?
Reach 70% conspiracy influence, intentionally miss specific charts, interact with diary entries, and pick the refusal at the right moment. Community spreadsheets on Steam and Discord list which diary numbers and trend thresholds you’ll need.
Extras
I left one achievement unfinished for weeks because it demanded nearly 24 hours straight of play. Extras are the game’s eccentricities — time, follower milestones, and mass exports.
These are the runs you plan for: 23:59:59 playtime requirements, gallery export counts, and astronomical follower totals. If you use Steam’s screenshot tools and the gallery export, you’ll make life easier for the Rim de Lacent and other export-based achievements.
| Achievement | How to Complete |

| HALP! | Reach 100% denpa |
| TOO CUWUTE! | Reach 999% DOKIDOKI |
| It’s pure chaos. | Reach 999% HYPE |

The game’s endings are a switchblade; one flick and paths split. Achievements form a trail of breadcrumbs through a fever dream. Which run will you try first and which ending will make you rethink everything?
